摘　　要：对通信网络射频信号的混合调制,能够高效提高通信过程信号的稳定性。对射频信号的混合调制,需要给出混合调制信号复包络表达式,对混合调制信号进行压缩处理,完成通信网络射频信号的调制。传统方法将不同射频信号通过一个激光二极管进行传输,获取射频分量,但忽略了对调制信号的压缩处理,导致调制效果不理想。提出新的射频信号混合调制方法,根据射频信号分离矩阵,依据定点递推法完成同址干扰去除。给出通信网络射频信号的复数表达式,建立相位调制函数,获取新的混合调制信号。为了提高计算效率,在给出混合调制信号复包络表达式的基础上,对混合调制信号进行压缩处理。通过混合调制信号损耗和抗干扰性分析可知,采用所提方法得到混合调制信号完整性和抗干扰能力高。The mixed modulation of radio-frequency signal in communication network can improve the stability of signal. Traditional methods ignore the compression processing for modulation signal, and the modulation effect is not ideal. Therefore, a mixed modulation method for radio-frequency signal was proposed. On the basis of separation ma- trix of radio-frequency signal and the mixed recursion, the co-site interference removal was finished. Then, complex eXpression of radio-frequency signal in communication network was given to construct the phase modulation function, and the new mixed modulation signal was obtained. In order to improve the computational efficiency, the mixed mod- ulation signal was compressed based on complex envelope expression of mixed modulation signal. Through the analysis of loss and interference immunity of mixed modulation signal, we can see that the mixed modulation signal obtained by the proposed method has high integrity and capacity of resisting disturbance.
